    Default opensuse lags when transfering large files

    I have been using opensuse for some years and one thing that irritates me is that when i transfer a large file from my laptop or desktop the whole pc is really slow.
    This has happend with bouth nfs and samba on my server which i transfer files to.

    OK, both PCI with DMA, and no USB. That's good.

    Transferring a 667 MB file over NFS using cp and wireless took about 3 minutes.
    While the copy was running, top showed the kernel thread (kworker) servicing the
    wifi took up to 13-14 percent of the time. Roughly 50% was spent waiting for I/O
    to complete. The processors still had idle time, and the keyboard/mouse response
    was OK. I have 2 CPUs that run at 2 GHz.

    If you have only one CPU, you would likely need to use "nice" on the process
    doing the transfer. Then regular priority tasks will get time.

    Not me.

    But there is another thread that complains about system slugishnes when
    copying large files over to usb.

    Or perhaps ionice, but is a bit complicated to use:

    Code:
    su root -c 'ionice -c 3 su YOURUSENAME -c "someheavytask"'
